allright so it seems to me if your air box has a second line like this pic:


that you have a secondary air intake...........my 2007 LT had this set up above........

i thought this only came on the 2006 cobalts....


so does that mean i cannot get a new header???

Red06LS

Sucks doesnt it. Not sure about the header tho but im sure some one will chime in.

Fken hate 2.2's (mine the most)................

Tank07

son of a bitch lol..........i do have GMPP intake..........all i did was get a filter for that line and secured it.......and ive never triped CEL........i dont understand how this effects headers though and yes i checked the thread..

Welcome to the wonderful world of emissions control...

I don't think anybody makes a header for SAI equipped 2.2Ls yet.

SAI is on all 2.2Ls sold in certain states.

Red06LS

Thats what my buddy did when he put his injen intake on. Looks ghetto as hell tho but it works...

Tank07

i got it tucked away nicely.......but wtf so now i cant go out and put on GMPP Performance Exhaust or a new header or a new downpipe?

this is bullshit...........and its a 2007 and not a 2006..........im pissed right now

Red07SSNA

Actually your 2.2L with SAI has a "header" -- steel tubes welded together, not a cast iron manifold. The SAI checkvalve sits on top of your exhaust manifold and controls when fresh air is injected into the manifold to reduce tailpipe emissions. No header manufacturer has made a header because they would have to include a mount for the checkvalve and include ports for the air to be injected as the stock manifold does. I don't think you'd be willing to pay what they would have to charge for this...

Tank07

this is just ******* great...........i didnt even think this was a problem since its the 2007 model had i known about the SAI i would have gotten a different 'balt to avoid this nonsense.......

Red07SSNA

SAI is on all 2.2Ls sold in certain states.

Tank07

well im in NY and there are plenty of 2.2s who have switched their header, downpipe, and exhaust...

im really not that concenered with header and downpipe as i am with the exhaust........but because of this emissions bullshit i cant even get a GMPP performance exahust?

or am i wrong?

Red07SSNA

No, you cannot put on the GMPP ext-honed manifold -- no place to mount the checkvalve. You can install the cat-back exhuast systems.

SAI is not a really a performance-killer, just a PITA for modding the exhaust.

ToyBoxCar

You can still get an exhaust without any problems at all. And you can go to a dealership and have them flash the ecu so that you can remove sai from your car, and then put your choice of header/downpipe on. So if you really want a header, just find a dealership, and have them flash the ecu

Red07SSNA

This is true, but you have to find a dealer willing to turn off the SAI in the first place. They can do it without reflashing the ECM -- can be done with the same equipment they use to enable 16" wheels on a Cobalt that came with 15" wheels.

Tank07

i know it dosnt kill performance........however it does kill the gains i would get from adding a new header and downpipe since that is not possible wit this SAI system

ya let well i do have a friend who works at a chevy dealer........maybe i can get it done there....

vB00STw

Thats so wierd.. On my Jetta, it has SAI and it only comes on on cold starts and goes off in 10-15 seconds. Alot of people I know just take them off so easy too..

brickerenator

i think hptuners can also take care of the SAI

Red07SSNA

If you can get it done, then you could remove the entire system - electric pump, checkvalve, exhaust manifold, hoses and tubes.

Tank07

great now how much work is that..........

hptuners do not support 2.2s.....

interesting.......im sitting in PHI 101 at the brook and i havent paid attention at all im so pissed right now lol

brickerenator

haha

my bad

Tank07

its all good........im just pissed right now this was one of those things i didnt expect because i have a 2007.......and my previous knowledge i had thought only the 2006 2.2s had this system..........

stupid emissions its all bs that does nothing but make our lives harder.......**** man-induced global warming is bullshit as it is and this is one of the results of that hysteria bullshit (yes this is against the trend statement, however i do have the facts that prove this)

Red07SSNA

Bunch of bolts and clamps..basic stuff.

Tank07

allright thats no big deal...im a DIY......im just pissed that i have to go to the stealership.......once my soundsystem/lambo door install is finished im gonna have a chat wit my buddy to see if i can get this done..........if not i guess im just not gonna change the header and downpipe

and guys seriously thnx for all the info

brickerenator

there's more global warming "truthers" than the media would lead you to think

Tank07

movie to watch: "the great global warming swindle" it was produced by the scientist who served on the UN's panel of climate control...

check it out weight the facts and then you will realize its all nonsens

/argument

allright now i have another question.........are there any 2.2s who have deleted this system?

and if anyone has........what steps did you do through to get rid of it.......

or is there already a thread that explains that? if so please post up the link

o ya and how much is removing the system gonna cost me?

brickerenator

do a thread title search for SAI
